[OPENMP] Codegen for 'omp critical' directive.
This patch adds codegen for constructs:
#pragma omp critical [name]
<body>

It generates global variable ".gomp_critical_user_[name].var" of type int32[8]. Then it generates library call "kmpc_critical(loc, gtid, .gomp_critical_user_[name].var)", code for <body> statement and final call "kmpc_end_critical(loc, gtid, .gomp_critical_user_[name].var)".

[mips] Correct alignment of vectors passed in varargs for the O32 ABI.

Summary:
Vectors are normally 16-byte aligned, however the O32 ABI enforces a
maximum alignment of 8-bytes since the base of the stack is 8-byte aligned.
Previously, this was enforced on the caller side, but not on the callee side.

This fixes the output of OpenCL's printf when given vectors.

Return true from UnifySection when emitting a diagnostic

Test Plan: I noticed this through code inspection.  The callers use the return value to remove the SectionAttr if a diagnostic is emitted, but I don't think the failure to do so is observable right now.

Fix a vftable mangling bug

We need to walk the class hierarchy twice: once in depth-first base
specifier order for mangling and again in depth-first layout order for
vftable layout.

Vftable layout seems to depend on the full path from the most derived
class to the base containing the vfptr.

Fixes PR21031.

Don't use comdats for initializers on platforms that don't support it

In particular, pre-.init_array ELF uses the .ctors section mechanism.
MinGW COFF also uses .ctors, now that I think about it. Therefore,
restrict this optimization to the two platforms that are currently known
to work: ELF with .init_array and COFF with .CRT$XCU.
